I am an older lady who decided to get rid of grays. But I wanted to be more unique. I also wanted to thicken my very fine hair. So I use permanent color in darkest violet on my roots. 3 days later I use Color Pulse Chill Plum. However I don't follow directions. I apply to dry hair early in the day. At that time I then wrap my hair with plastic wrap. Leave it on for at least 4 hours. Then rinse my hair til at least 95% clear. I do this every 40 days. The results are amazingly beautiful and glossy dark violet plum. Goes great with my light blue eyes!
